       </DataTemplate>

       <DataTemplate x:Key="DataTemplate_Level1">
           <ItemsControl ItemsSource="{Binding}" ItemTemplate="{DynamicResource DataTemplate_Level2}">
               <ItemsControl.ItemsPanel>
                   <ItemsPanelTemplate>
                       <StackPanel Orientation="Horizontal"/>
                   </ItemsPanelTemplate>
               </ItemsControl.ItemsPanel>
           </ItemsControl>
       </DataTemplate>

   </UserControl.Resources>


   <Grid>
           <StackPanel Orientation="Horizontal">
               <ItemsControl x:Name="lst"  ItemTemplate="{DynamicResource DataTemplate_Level1}" />
           <Button Click="Button_Click" Content="salva"/>
       </StackPanel>
   </Grid>

codebehind:

 

DB_Crew1Entities entita = new DB_Crew1Entities();
        List<OperazioniBettolina> row;
        List<List<bool>> lsts;

        public UC_Orari()
        {
            row= entita.OperazioniBettolinas.ToList();

            lsts = new List<List<bool>>();

            for (int i = 0; i < row.Count(); i++)
            {
                lsts.Add(new List<bool>());

                for (int j = 0; j < 30; j++)
                {
                    //fill range of checkboxes read from db
                    lsts[i].Add(row[i].StratTime<= j && j < riga[i].EntTime);

                }
            }

            InitializeComponent();

            lst.ItemsSource = lsts;

        }

 

How can i write on db?

 if the user check other checkbox i should save another(new) range ::

 

private void Button_Click(object sender, RoutedEventArgs e)
        {
            for (int i = 0; i < lsts.Count(); i++) ????
            {
              ???????????????????????

            }
        }
